These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure.

To maintain contaminant-free standards in clean room environments, these valves come cleaned and bagged to Fed. Std. Class 100 and ISO Class 5 clean room standards and have a 316 stainless steel body with a smooth finish to resist dust collection.

Prevent changes to your pressure setting—these valves come set at a nonadjustable outlet pressure.

Valves have a brass body and NPT connections.

Change outlet pressure without using a gauge—turn the dial to adjust the outlet pressure in 5 or 10 psi increments.

Withstand more than six times the inlet pressure of standard pressure-regulating valves.

A 316 stainless steel body provides exceptional corrosion resistance in wet conditions and harsh environments.

Withstand inlet pressures up to 3,500 psi.

Our smallest pressure-regulating valve.

These valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure.

Reduce contaminants in gases used in research sample systems, emission monitoring systems, chromatography, and other high-purity applications. These valves have a 316 stainless steel and brass body with a smooth finish to reduce dust collection and internal components designed to protect the seal and diaphragm from contamination.

Commonly used in TIG welding where gas flow/coverage is a concern.

A 316 stainless steel body provides exceptional corrosion resistance in wet conditions and harsh environments.

Designed to reduce contaminants in high-purity applications using hydrogen and methane gas, these valves have a stainless steel and brass body with a smooth finish to reduce dust collection and internal components designed to protect the seal and diaphragm from contamination.

Designed for oxygen service and other high-purity applications, these valves can withstand the extreme cold of liquid argon, liquid carbon dioxide, liquid nitrogen, and liquid oxygen.

Body is brass or nickel-plated brass. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

For corrosion resistance in wet conditions and harsh environments, these valves have a 303 stainless steel body. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

Change set pressure to suit your application—this valve includes four interchangeable color-coded springs with different set pressure ranges.

Our only valves that meet ASME Code Section VIII for use with cryogenic pressure vessels. They are for use with argon, carbon dioxide, helium, hydrogen, methane, nitrogen, and oxygen.

Alter the set pressure to suit your application.

Change set pressure without guesswork—the adjustment screw is marked in 25 psi increments for making pressure adjustments without a gauge.

A finely threaded adjustment screw lets you make precise set pressure adjustments.

For precise control over your vacuum level, these valves have ±0.1% accuracy.

A 316 stainless steel housing allows these regulators to withstand corrosive environments in the semiconductor, marine, chemical, instrumentation, and paper industries.

A stainless steel housing and bowl allow these filter/regulators to withstand corrosive environments in the semiconductor, marine, chemical, instrumentation, and paper industries.
